Patented May 6, 1930 PATENT OFFICE LOUIS LUMIERE, OF LYON, FRANCE TALKING MACHINE Application led April 301925, Serial No. 27,023, and in Great Britain May 26, 1924.

This invention relates to improvements in talking machines and in particular to improved means for mounting diaphragms of large diameter, so thatthe diaphragm may,

when not in use, be turned down from its playingjposition to lie substantially parallel with the record to enable the lid of the cabinet tobe closed.

According to the present invention a talklu ing machine is provided in which-the diaphragm, mounted at the free end of a carrying member capable of swinging across the record, lies during the playing in a plane substantially at right anglesto the longii tudinal axis of said carrying member, said diaphragm being also capable of rotation about a horizontal axis to occupy a nonplaying position substantially parallel with the record.

The carrying arm is preferably extensible so that the distance between the stylus and the vertical axis about which the carrying arm moves can be varied. The diaphragm is mounted on the free end of the carrying 25 arm so that it can be turned, to occupy different positions, about a horizontal axis lying at right angles to the longitudinal axis of the carrying arm and lying parallel to and close to the plane of the diaphragm,

and this horizontal axis lies near the lower edge of the diaphragm when the latter is in the playing position. Means are provided which clamp the diaphragm when brought to the playing position, and hold it tight .5 against the rigid horizontal carrying arm. This clamping means may take the form of a strong spring fork mounted on the horizontal supporting arm, between the arms of which is forced a lug or block mounted at the back of the diaphragm holding ring, when the diaphragm is brought to the playing position.

By means of this arrangement the diaphragm when in the playing position is supported close to and behind the lowest portion of the diaphragm holding ring, on which is mounted the vibrating needle holder.

The invention is illustrated in the accompanying drawings in which Fig. 1 is a side elevation of a talking ma chine with the diaphragm in the playing position,

Fig. 2 is a similar view to Fig. 1, but with the diaphragm in the non-playing positi on,

Fig. 3 is a plan view partly in section showing the construction of the carrying arm, and

Fig. 4 is a view on the line 4--a of Fig. 3 loolring from the right.

Referring to the drawings, on the motor boa-rd at the rear of the turntable `1 is mountcd a plate 2 carrying a short, rigid, vertical shaft 3 which forms a vertical axis for a cup-shaped member 4:. Between lugs 5 on one side of the cup-shaped member is mounted a plate 6 adapted to rock about a horizontal axisformed by bearing screws 7 carried in lugs 5.

To the plate 6 are secured two long tubular members 8, 9, to form a part ofthe diaphragm carrying arm, and a relatively short tubular member 10 the purpose oi which will be de` scribed later. Within the tubes 8, 9, slide rodsill, 12, having piston like ends 13 which are a sliding lit within the tubes 8, 9. The rods 11, 12, at their outer ends slide in stutfing `boxes 14, carried together with a spacing plate 19 at the ends of the tubes 8, 9. Felt rings 32 are provided inside the stuffing boxes to provide :tor a smooth but not too tree slidingmovement of the rods 11, 12. At the outer end of the rods 11, 12 a yoke-shaped 1nember"15 is mounted (Figs. 3 and 4) and at the extremities of this member lugs 16 are formed to carry screws 17 which form bearings for the diaphragm by taking into studs 18 carried on the diaphragm ring. The studs 18 may with convenience be formed with holes 20`which take over the screws 21 by means of which the spider 22 is secured to the diaphragm holding ring 23. O11 the main portion of the yoke-shaped member 15 is mounted a clip device 24 adapted, when the parts are in the playing position to engage with and grip a block 25 carried on the diaphragm ring 23 to retain said diaphragm in the playing position. Preferably a spring pressed plunger 26 is provided, said plunger projecting through the side of device 24 to engage with a depression formed in one side face of block 25. Y

The member lO referred to above comprises Van outer sleeve in which slides a plunger 27 ing position and the diaphragm is inthe ver-V tical position, the reproducing needle 3l will swing from the edge 'of the record towards the centre. When the machine is vto be closed the diaphragm is 4drawn forward, the' rods 1l, l2, sliding in the tubular members 8,- 9,

and the diaphragm is then turned back about the horizontal axis formed by bearing screws 17 until it rests upon the carrying arm, the clip device 24, 26, being disengaged, and the diaphragmV in the horizontal position lies substantially over the turn-table.

I claim:

Y l. In a talkingmachine of the type having a record tablet and a diaphragm of large diameter adapted to operate without a sound arm and operatively connected to a stylus, a support, a carrying member mounted on said support and capable of Yswinging across the record tablet under the action ofthe stylus moving in the sound groove, means for mounting said diaphragm on the carrying member whereby said diaphragm lies during playing in a` plane substantially at right anglesto the longitudinal axis of the carrying member, and means pivotally connecting said diaphragm to said carrying meansV whereby said diaphragm may be moved about a horizontal axis to occupy a non-playing position lsoubstantially parallel with the carrying memv2. A talking machine as claimed in claim 1, wherein the carrying member embodies telescoping elements capable of being extended and contracted to vary the distance of the diaphragm from the axis of rotation of Vsaid carrying member.

diaphragm to hold it in the playing position.

l 6. A talking machine as claimed in claim 1, including a yoke-shaped member carried at the end oi the carrying arm, the extremities of said yoke-shaped member having lugs in which the diaphragm is pivotally mounted at a point near its edgeto rock about a horizontal axis, a member carried by' the diaphragm rim, and a spring clip or like device provided upon said yoke-shaped member and adapted to engage with said member carried by the diaphragm rim to retain the diaphragm in the playing position.

7 A talking machine as claimed in 'claim l, embodying yielding means for holding the diaphragm in the playing position said yield.- ing means being carried by the carrying member and adapted to operatively engage' the diaphragm near the lower edge of the same.

8. In a talking machine of the typejemploying a diaphragm of large diameter, a pivotally mounted arm for carrying said diaphragm comprising a plurality of telescopically engaging elements, a pair of said elements being provided with longitudinal pivot members havingaxes which engage the diaphragm adjacent the lower portion thereof and which are disposed substantially at right angles to said elements. y

In testimony whereof I have name to this specification.
